EXCESS HEAT DURING DIFFUSION OF DEUTERIUM THROUGH PALLADIUM
... Input power is measured accurately since the heater is driven by a DC power supply. Output power is measured via the temperature difference given by two thermistors, one at the inlet, and the other one at the outlet with a precision of +/- 0.01 K.

Heat transfer
Heat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat. The fundamental modes of heat transfer are conduction or diffusion, convection and radiation.Heat transfer always occurs from a region of high temperature to another region of lower temperature. Heat transfer changes the internal energy of both systems involved according to the First Law of Thermodynamics. The Second Law of Thermodynamics defines the concept of thermodynamic entropy, by measurable heat transfer.Thermal equilibrium is reached when all involved bodies and the surroundings reach the same temperature. Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
